:Beit known, "that I, CHRISTOPHER I-IOGLAND, of Delavap', in thc countyof Tazewell, and State of Illinois, have invented a new and improvedCultvator; and( dohereby declare that the following'is a fullyclear, and

had to the accompanying drawings forming part of this specification;`

Figure 1 is a top view o'f my coltivator.

This invention relates to the improvement of oultivatorsby. jointing thestandardsbearing the ploughs, and attaching links1 to the same, sothat'the former can'be raised clear of the ground when' desired,togetherwith other devices improving andpertectiug the whole. i Y 1 I T is thetongue. A -is the generalfram of the cultivator, having the swingingstandards C attached to it,-

exact description thereof, which willelnable others skilled in-thefartto make'andiise the same, reference being with eye-bolts, as 'shown atS, whereby the said standards are Vallowed a partial vibration-on theircentres ofl attachment n any'direotion. 'B-B are thewheels,and Dtheaxle, supporting the frame A. E is the seat,

supported byarehed iron rods F, secured to the frame A. The rearstandardsV C C' are held to the frame by a transversarod, G',and-haveonly a forward and baclmjard vibration. 'Another rod, H,'passes throughtheir upper ends, and hollsthem steadyby means of nuts'afand washers b.j .lA-rod, I, bent, as shown at-J, is pivpted in mortises in the 'upperendstofthe standards C fera purpose tof be shown.. Thisrodis providedwith two or more holes `Vfor adjsting the spread of'4v the standa1dsThis `rod is further 'provided with a V-sha'ped link, K, to which isattached a .flink orlrod, Z,'oonneeting it with therod H, for a,vpurpose to be explained. 'The lower ,ends ofall the standardsarejoin'ted `at d bymeansof side-plates e, bolted to the upper part`s,and having a/single bolt, f, passing through each one of thelo'wer partsCU', whereby the latter are hingedto the-upper-parts. The proximate endsof the two parts are formed with :1t-corresponding angle, as shewn bythedotted line, by means .'tflwhica'whsn trotghtin une, the said ptits' win.te heidstiny. `The object of this joint or' hinge is to snow ithe'ploughsto be brought forward and raisedclear. ofthe ground whendesired.A This is accomplished by the attachment oflinks K to eye-boltsg, nearthe ploughs; the other ends of said links being-similarlyattached to Y *the frame A 4at 4some part forward of the ploughs. Thedriver, 4when desiring to raisewthe ploughs-I? P clear of theground'presses the upper ends of the standards C forward'with his feet.The link'sK ofthe said standards raise the ploughslD P., as shown by thered outline in iig. The connecting-link Z also brings 'forward the`rearstandards C CQ and their.links K in 'like manner raise the ploughs P'P".l The lateral vibration of the front p standards CV Cihasjfor itsobject'the avoiding of irregular.hillsA of corn or. other. growth, bydviating the plohghs P to the rightv or Ieftof such irregular hills whenenouiitered. This lateral movement isgiven to the' ploughs by the driverby means of anuprightrod L resting .i'n `the bend J. of the cross-rod I.This upright, L,is bent at it-'right angle, one part of which-passesloosely under a plate, M, bolted on to the axle D, as shown-in figs. Il.

and 2. VThis upright, L, is thus .permitted a lateral vibration. Afterpassing under thevplate M, 'thesaid rod "bifurcates intotwoarms'N,`whieh are dattened andturned u-pat their ends to form arest'or pedal for thedrivers foot, Vas sho-wn'at ligsl and-3. Bypressing down either one of these pedals, the upright, L, be means ofits location in the bend J, moves the Astandards Ofand consequently theplolighs P, to the right or left,as`before mentioned. A spring, O,`fastened to the frame, and bent in the form of a catch, as shownat gs.Zand 3, catches on to a crossgpieoe, u, pivoted on to the standards GC', and holds all the standards forward, and consequentlythe ploughs Pabove the ground, for the purpose .before shown. To each standard isfastened a scraper,'9', formed of two parts g g, one Yof .whichison eachside of the links K, which thus keepst it in place. At their ends, andrestingon the front of the ploughs,is the scraping-edge 1' for cleaningthe yplough-point's when clay or stii soil is collected thereon. i-.Whenthe ploughs are raised out of the ground inthe mannerbefore shown, thisedgar bears upon and vpasses along the face of the plough as the same israised, thus'scraping it lear. The links =K to take a portion of thestrain from the staudarcljoints d when 'ploughing This form 'ofcultivator presents many advantages over those new in use, being lightrif-draught, simple;

L cicient, neasily operated, of "small oost, and little likely to getoutof repair.

I claim as new, and desire to secure by Letters Patent- 1. Thecombination of the jointed plough-*standards C C', plates'd, links K,scrapers'r, and connectinglinks lk, as herein described, for the purposespecified. l

2. The links Ik, or other equivalentI device, for conneeting'the frontand rear standards, for the purpose of operating the lattersimultaneously with the former, 'substantially as shown and described.

3. The plates with their boltsf, or other equivalentdevice, for forminga hinge between the standards C C and plouglis P P', substantially asshown and described.

4. The spring-catch O, or its equivalent, for holding the standardsforward, substantially as and for the purpose shown and described.

5. The rod L, for vibrating the standards C laterally, substantiallyrasshown and described -6. The arms N, for operating therod L,substantially as shown and described.

7. The rod I, with its bend J,.or other equivalent device, substantiallyas and=for the purposes shown an described.

8. The laterally-vibrating standards C, iu combination with the rod Land bend J, substantially las and for the purposes shown and described.

9. The ploughfcleaner r, or other equivalent device, attached andworking .substantially as shown and described.
